Our power is handed to us at 480v. We then deliver it to the customer at whatever they need. The nice thing about 120v is that everything uses it. No odd cords (as mentioned before) or expensive PDUs. I've had a lot of people suggest that running our servers at 240v would save us money because we'd use less amps. Last time I looked at my bill I was being billed by the kWh, not amp and 240v at half the amps is still the same wattage. I've been told this so many times though that I'm starting to doubt myself. If anyone can present a reason for me to switch to 240v I'd like to hear it.

I have a pure curiosity question for the NANOG crowd here. If you run your facility/datacenter/cage/rack on 120 volts, why? I've been running my facility at 208 for years because I can get away with lower amperage circuits. I'm curious about the reasons for using high-amp 120 volt circuits to drive racks of equipment instead of low-amp 208 or 240 volt circuits. ~Seth
